| Site EPIRB, Transect 2 | 1.72 (0.07) | 83 | 0.73 | 3.21 | 28.47 |
| UK-1 Stratum A (Site 6) | 1.31 (0.04) | 110 (170)& | 0.70 | 3.31 | 31.87 |
| AB01 (Sites 6 and EPIRB) | 1.48 (0.05) | 136 (180)^ | 0.69 | 3.25 | 28.62 |
| Station M | 0.29–11.1 | 102 | 0.6–0.9 | 2.5–3.3 | — |

The AB01 values were obtained using only the imagery from the quantitative analyses. &This value was obtained using all imagery from UK-1 Stratum A. ^This value was obtained using all imagery from AB01. *This value is for Es(103). Values for Station M are from Khunz et al. (2014) and PAP values are from Durden et al. (2015). s.e. = standard error.
